In an electrically heated home, the temperature of the ground in contact with a concrete basement wall is 11.9 °C. The temperature at the inside surface of the wall is 19.0 °C. The wall is 0.13 m thick and has an area of 7.5 m². Assume that one kilowatt hour of electrical energy costs $0.10. How many hours are required for one dollar's worth of energy to be conducted through the wall? Number i Units
